The proposed water supply pipeline will be approximately 1100 feet of 6 inch <br />plastic pipe buried approximately 5 feet below ground surface. A northeast trending drainage <br />will be traversed near the middle portion of the pipeline run, approximately 615 feet west- <br />northwest of 2010-26-198-2C well. The water supply pipeline will span the drainage incased <br />and insulated within a length of 9 3/8 inch casing. The drainage will be spanned approximately <br />5 feet above the bottom of the drainage. Two check valves will be installed to prevent backflow, <br />one each in the new and existing water supply lines. Attached to this letter please find an aerial <br />map of the proposed pipeline path. Reclamation efforts for disturbed land associated with the <br />pipeline construction will commence this fall. <br />Should you have any questions or comments, please contact me at (970) 254-1224 or (970) <br />216-1010 (c), or Bob Warneke at (970) 878-3674 ext. 14. <br />Regards, <br />7 <br />Gerald J.
